Need some ideas.

I have a flat bed 1 ton dump truck. If I was to hook up to my 18' open trailer what is the best way to build a ramp to connect the two? In Turf Mag there is a advertisment for a "Load And Go" ramp from www.usaramp.com, but the capacity is only 1200lbs. I would like to build it out of wood using 4- 4x4x8 or 6x6x8 with 3/4 in. plywood drilled to the top to make a ramp but I am open for suggestions. I would be driving a 60in. Lazer Z w/ UltraVac on it. Just the mower with me on it weights 1320lbs. I figure with a load of leaves plus the vac and counter balancing weight it would weight about 1800lbs. It would work like the walkers with the new QDS UltraVac installed. This ramp will only be used the rest of this season which seems like its going to last until Jan. Next year we are going to build a box on the truck and buy a leaf loader.
